张家川回族自治县肉牛、绵羊支原体肺炎流行学调查

Epidemiological Investigation of Mycoplasma Pneumonia in Beef Cattle and Sheep in Zhangjiachuan County of Gansu Province

近年来,由于肉牛、绵羊支原体肺炎的传入,给张家川回族自治县肉牛、绵羊养殖产业造成巨大的经济损失。支原体肺炎,是由于感染支原体而引起的高度接触性传染病,主要以飞沫经呼吸道传播,也可通过直接接触传播。本研究采用ELISA方法检测肉牛、绵羊支原体肺炎在该地区的感染情况,较全面地反映其流行特点。肉牛、绵羊支原体肺炎在张家川回族自治县东部、中部、西部15个乡镇均有发病;肉牛的总感染率(8.98%)低于绵羊的总感染率(10.46%)。
